Whole House Surge Arrester

I was looking into getting a whole house surge arrester.  The only issue that I ran into was the limited warranty of 5 years.  Basically - what that means is that I will have to change out/replace the arrester every 5 years (by a certified electrician) if I want the warranty.  It's probably $150-$200 labor cost to install (plus the cost of the arrester ~$200), but still seems like an unnecessary expense. I looked around, but it seems that the 5 year warranty seems pretty standard.  Anybody install one with a 10 yr/> $50k warranty?

Thanks in advance.
